Hard to find the Tri-State Marker, but it was cool when we found it!

Tri-State Monument.

Stand on Three States

The monument has recently been painted and the guardrail fence updated.

[Bev Watkins, 07/02/2019]

The monument is minimalist, but few tri-state boundaries are marked with a monument, and even fewer are right next to a road.

Monument is very aged. and the white base is corroding. Now has guardrails. If you geocache, there is one we found by fluke!

Tri-State Monument.

This is a very small marker in a field.

[Jill, 07/02/2016]

The tri-state monument used to be in the middle of a road, but cars kept hitting it. After several run-ins this monument was moved off to one side. You can stand at the new spot and the old spot (as long as there's no traffic).
